Blockchain and Smart Contracts in Insurance

Blockchain in Insurance

Blockchain technology offers potential applications in insurance through its distributed ledger capabilities. In theory, blockchain could improve data sharing between insurers, reinsurers, and brokers while maintaining data integrity and auditability. Claims history stored on a blockchain could reduce fraud by providing an immutable record of past claims across carriers. Identity verification, policy administration, and subrogation processes could become more efficient through shared, trusted data sources. Several industry consortia have explored blockchain applications, though widespread adoption remains limited by technical challenges and regulatory uncertainty.

Smart Contracts and Actuarial Implications

Smart contracts are self-executing programs stored on a blockchain that automatically enforce contract terms when predefined conditions are met. In insurance, smart contracts could automate claims payment for parametric products (triggering payment when a weather station records qualifying conditions) or process straightforward claims without human intervention. For actuaries, smart contracts raise questions about how pricing and reserving should account for the elimination of claims handling expenses, the reduction in claims leakage, and the potential for faster loss development. The technology also creates new risks around coding errors, oracle reliability, and regulatory compliance that actuaries must consider.
